ligure 4l is a detail sectional View along l-fl`oilf l'ic'ure 1; and l i litigare illustrates a inodilied construction el an end tintura p p i i fthe rod comprises the telescoping or overu lapping sections and 11, thesersectons beinp; open at their outer ends and engageable through a sprins)n connecting member 12 with the end 'fixtures 13; rthe resilience ol'A the spring; oenibers 15J adapts them to trietionally engage the inner `Weils of the sections 1U and 11 to hold the end ixtures in position and. at the same time permit retati-on oit the telescoping sections with re speci; to the end. iintures. These tixtures may lie liu'thei.w `provided *with prongsliadapted to be liorced .into the supportan@` structure 15 which may be a doorway arch,

window :traine or 'the like.

tine et the sections as the section. 11, is provided. with threaded member or screw rod 1G upon which. is `in ouuted the friction locitinp; element orexpansible clutch 17. lhis clutch as shown inuliipgure is termed oit the Wings or expanding portions 18 con struct-ed. at one end to receive a vnut 1) threadedly manageable with the rod 1G.' The other end o1E the clutch .17 is adapted to 'lirictionally engage the inner wall of the section 10 and for maintaining a ifrictional )annulent o'l the wiiug's 18 with tl1e`section l@ l: have provided a tapered expand ing element E slidably engageable with. the rod 1G and urged longitudinally o1 the rod to expand the Wings 18 by reason of a spring` 21-` 1inl .the unlocked position o1 the parts, the wings 11B ot the clutch 17 slidably and :frictionally engage the Walls oit the section 10, the Friction established by the spring 2l acting on the 'tapered expanding element 20 being;l insuiiicient to ijn-event relative iongitiulinal increment of the sections 1() and 11, but being` sutiicently great so that when one ot' the teiescopiaii;i sections is rotated With respect to the other the Wings 18 will be held fixed With the section 10. Thus when it `desired to position the hanger rod :tor use the sections 10 and 11 are longitudinelly separated approximately to their linal positions with the end iixtures 13 engaging the sides oit the arch or window :traine 15. lheu `one ot the sections, as the section 11, is rotated `with respect to the section 10 and because ot the 'friction between the Wings 18 and` section 10 the clutch 17 will not rotate with the section. 11 and rod 1G,` butthrouglr the n.11t19 en raging the rod` 1G will be caused to travel longitudinally oit the rod 1G to the lett as shown in Figure 2. This movement oit the clutch causes the ends et the Wings 18 to be firmly wedged "between the expanding element 2O and the inner Wall ot `the section 110 whereupon further rotation of the section 11 Will cause the sections 10 and 1l `to be relativelyoutwardly moved. i During this outward inoveinent of the telescopio sections, the clutch 17 is firmlyclainped against rotation or longitudinal movement by the @K ijiaiiding element 20 acting to ein pand the Wings 18 against the section '-10 As `the sections are in oved `outwardly the sprint); 2l. `Will be compressed so `as to still :further increase the clamping etl'ect of the element 20. The limit b'ttravei of the section `11 With respect to the section lois dcterniined by the amount ot compression the spring' can i take. 1n this manner the the telescopic sections are forced out vardiy troni'each other causing the projections lft ofthe iizrtures 13 to bite into the Walls 15. ln removing` the hanger rod it is merelji7 necessartT to `relatively rotate the sections 10 and 11 in the opposite direction whereby tlieparts will be restored to theirunlocked positions permitting tree longitudinal movement oi. the .sections 10 and 11.

The spherically shaped fixtures 13 being `engagedby the open ends of the rods l() and ll, it Will be apparent that a universal movement is afforded at the ends of the rods. Thus, the rod will automatically adjust itself to uneven surfaces such as slant -si'ibst'ance 22 for f'rictionally engaging the Wall l5 Where it Would be undesirable to -mar thel wall l`as by penetration of the projections 14Ck inthe form illustrated in Figure 4f.'

It will be noted that I have provided a simply constructed hanger rod'vvhich may be quickly attached ,to opposite supporting surfaces without requiring ,the use of supportingbrackets fixed with these supporting surfaces. Y

While itis believed that from the foregoing description, the nature and advantage of my invention Will be readilyV understood, I rdesirefto have it understood that I do not limit myself to what iis herein shown and described and that `such cha-nges'may be resortedto ivhe'n desired as fall Within the scopeojf `the claims.- 'y

l lVhat I 'claim as my invention is -l. vA'hanger rod comprising a pair of telescopically Varranged, relatively Aslidable and rotatablesections engagea-ble at their' outer ends 'with a supporting surface, locking means carried bygone of said sections and frietionally engaging `the other permitting relatiivensliding of the sections when unlocked, said-sections being llocked against relative slidingby said locking'means upon rotating one of said sections with respect t0 the Zother, vand means effective upon continued relative rotation for positively feeding one section longitudinally of the other.

2. A 'hanger rod comprising a pair of telescoped sections, a threaded member fixed to one ofsaid sections, an element vfrictionally engageable With the second section and normally Llon'gitiu'linally movable with the. first section, Iand means effective upon a relative rotative 'fmovement'of said sections at various'positions of Vtheir longitudinal adjustment forclutching'the friction element with f the second section whereby upon continued relative'rota-tionofthe sections the threaded member :will act to .positively and relatively Alongitudinally move the sections.

A hanger rod comprisinga pair of tele- Vscoped sections, a threaded'member fixed to one of `sa'1d-sect1ons,an element frictionally engageable Wit-h the secondsection and normally longitudinally movable With the first section, an element threaded for engagement with the said tlneaded member and connected to move the said friction element, and means including an expanding clement effective upon a relative rotative movement of said sections at various positions of their longitudinal adjustment for causing the cxpanding clement to move the friction element into locking engagement with the second section, continued relative rotation oi; the sections thereafter causing travel of the threaded element with respect to the fhrcaded member and first section to positively and relatively longitudinally move the sections.

8. A hanger rod comprising a, pair of llll) lll overlapping sections, one of said sections being open ended, an end fixture having a splierically shaped portion slidably engageable with the open end of said rod, said lixture provided with prongs engageable in a supporting surface, and means for posi tively longitudinally separating thesections to torce the said prongs into the said supporting surface.
